Write to File without destroying previous data

[Serpha]

Does anyone know how I can write to a file while preserving the data already in that file. I know that one way possible would be to first read in all the data from that file first, then output old and new data together but that would not be desirable in this case as the data file could be very large.

Thanks

When you create your FileWriter, set the append flag to true. This means that any data you write is written to the end of the file.

FileWriter myfile = new FileWriter("thefile.txt", true);
